326. A 24-year-old is undergoing open reduction of an ankle fracture under general anesthesia with
sevoflurane, N2O, and O2 through a laryngeal mask airway (LMA). Just after the vaporizer dial is
turned up to 2%, the patient begins spontaneously breathing, but the inspiratory valve is not fully
closing. The likely result of this (malfunctioning valve) is an increase in the inspired concentration of
2
A. N2O
B. CO2
C. O2
D. All of the above
The reason CO2 measured by capnometer is less than the arterial Paco2 value measured

A 25-year-old healthy patient is anesthetized no flow of O2 through the O2 rotameter
for a femoral hernia repair. Anesthesia is
maintained with isoflurane and N2O 50% in
O2 , and the patient's lungs are mechanically
ventilated. Suddenly, the "low-arterial
saturation" warning signal on the pulse
oximeter gives an alarm. After the patient is
disconnected from the anesthesia machine,
he undergoes ventilation with an Ambu bag
with 100% O2 without difficulty, and the
arterial saturation quickly improves. During
inspection of your an
A sevoflurane vaporizer will deliver an vapor pressure
accurate concentration of an unknown
volatile anesthetic if the latter shares which
property with sevoflurane?
A. Molecular weight
B. Oil/gas partition coefficient
C. Vapor pressure
D. Blood/gas partition coefficient
If the internal diameter of an intravenous increased by a factor of 16
catheter were doubled, flow through the
catheter would be
A. Decreased by a factor of 2
B. Decreased by a factor of 4
C. Increased by a factor of 8
D. Increased by a factor of 16
Vaporizers for which of the following volatile halothane and isoflurane
anesthetics could be used interchangeably
with accurate delivery of the concentration
of anesthetic set on the vaporizer dial?

If the anesthesia machine is discovered change the CO2 absorbant
Monday morning to have run with 5 L/min of
oxygen all weekend long, the most
reasonable course of action before
administering the next anesthetic would be
to
A. Administer 100% oxygen for the first hour
of the next case
B. Place humidifier in line with the expiratory
limb
C. Avoid use of sevoflurane
D. Change the CO2 absorbent
The capnogram waveform above represents incompetent expiratory valve
which of the following situations?
A. Kinked endotracheal tube
B. Bronchospasm
C. Incompetent inspiratory valve
D. Incompetent expiratory valve
Which of the following would result in the intravenous injection of methylene blue
greatest decrease in the arterial hemoglobin
saturation (Spo2 ) value measured by the
dual wavelength pulse oximeter?
A. Intravenous injection of indigo carmine
B. Intravenous injection of indocyanine green
C. Intravenous injection of methylene blue
D. Elevation of bilirubin

helium. Isoflurane 2% is added to this
mixture. What effect will helium have on the

concentration?
Which of the following combinations would Sevoflurane vaporizer filled with
result in delivery of a higher-than-expected halothane.
concentration of volatile anesthetic to the
patient?
At high altitudes, the flow of a gas through a greater than expected at high flows but accurate at low flows

A. Greater than expected
B. Less than expected
C. Less than expected at high flows but
greater than expected at low flows
D. Greater than expected at high flows but
